If you stick with well-reviewed independents (who are much less likely to be bait and switch artists), you shouldn't have a problem. If you go with some hottie off Craig's List or the back of the newspaper, God only knows what you might end up with and who might be waiting behind the door!
Big lesson here: get a VIP membership and do your homework!

she is not what you had in mind and give her $50 for gas. If you do the resaerch on these boards this should not be an issue and remeber if it looks to good to be true

Depending on how misled I felt, I would take one of the following actions:

1. Total B&S, equals no cancellation fee. I would not give a single red cent. It only encourages the tactic.

2. Old or oudated pics, I would give a small cancellation fee. something on the order of $20-$50.

As far as some gorilla breaking your legs. At home I have little fear of that. I live in a town where it is required that it's residents own a firearm. I would simply call the police to pick up the body.

In Vegas it's a different story. I would suggest that if you're staying in a major hotel/casino, you're not in much danger. The security, video survelliance, guards, etc. should dissuade that type of behavior. If your staying in a fleabag without security, you might want to use your own judgement.

One other word of advice. Vegas agencies are notorious for hounding you after your date ends. It is not unusual to get six or seven calls from other ladies trying to set up other appointments. I would stick to well reviewed independants.

That said, say hello to my money and happy hobbying.
